SPECIFICATION forming part of Letters Patent No. 651,929, dated June 19,1900.

Application filed August 22, 1899. Serial No. 728,077. (No model.)

To a, whom it may concern:

Be it known that I, ERIK Q. OLSON, a citizen of the United States ofAmerica, residing at Greensburg, in the county of Westmoreland and Stateof Pennsylvania, have invented certain new and useful Improvements inMultiple Vises; and I do hereby declare the following to be a full,clear, and exact description thereof, reference being had to theaccompanying drawings, which form a part of this specification.

My invention relates to an improved multiple vise; and it consists incertain details of construction and combination of parts, as will befully described hereinafter.

In the accompanying drawings, Figure 1 is a side elevation of myimproved vise, which is constructed and arranged in accordance with myinvention. tion of the same. Fig. 3 is a plan view. Fig. 4 is anenlarged detail sectional plan View of a portion of the vise, saidsection taken through the center of the working parts. Fig. 5 is anenlarged sectional end view showing the manner of clamping the vise tothe bench. Fig. 6 is a plan view of one of the jaws.

To construct a multiple vise in accordance with my invention, I formfrom cast metal an annular base-plate 1 of a suitable size and havingformed therein several openings for the-reception of bolts 2, wherebythe said base may be firmlyattached to thework bench or table 25.Arranged upon the top of this base-plate 1 is a frame 3, also annular inform and provided with a semicircular recess extending along the top forthe reception of a hollow cylindrical shaft 4, upon the forward end ofwhich are formed the three single vise-jaws 10, 11, and 12, cast upon ahead 9,integra1 with the shaft 4. This shaft 4 and head 9 may berevolved or turned in the bearing and are prevented from lateralmovement by the head 9 upon the one side of the bearing and a collar 4,formed upon the other. The shaft 4 is confined in its bearing andprevented from rotary movement by a yoke 6, surrounding the same andengaging with the saddle-piece 5, resting upon the top of the shaft.This yoke 6 is provided with a shank 20, threaded at its lower por- Fig.2 is a front elevation and extending downward through the frame 3,*thebase-plate 1, and the table 25, and is provided with a hand-nut 21, bymeans of which the parts maybe made rigid the one with the other.

The interior of both the saddle-piece 5 and the semicircular bearing(see Fig. 5) for the shaft 4 are formed with a series of parallel ribs 7and 8, extending in the direction of the length of the parts, and serveas a means of gripping the shaft 4 when pressure is placed upon the yoke6. g

To hold'the frame 3 and base 1 together when the vise is detached fromthe bench or table, a groove is formed at a suitable point about theshank 20 and beneath the base 1 and an ordinary springn'ing 22 placedabout the same.

Operating within the bore of the shaft 1 is another and similar shaft13,1capable of being moved in the direction of its length by means of athreaded shaft 15,passing through a threaded boss 14, attached to theinner periphery of the shaft 4,and operating through a slot 13, formedalong the inner shaft 13. This threaded shaft 15 is provided at theouter extremity with a head 16 and crossbar 17 and is prevented fromlateral move ment by a piece 19, attached to the head 9 and engagingwith a groove 18, formed in the said threaded shaft.

Formed integral with the inner shaft 13 are three vise-heads 10, 11, and12, corresponding in shape and construction with those of the outershaft 1.

The jaws 10 and 10, forming the one vise, are of a peculiar form bestadapted for any special work. The second vise l1 and 11 is of theordinary form, and the third 12 and 12' 0 provided with an adjusting-pie'ce 26, (see Fig.

6,) arranged in a socket 27 and may be set at any angle by means ofshort set-screws 28, thereby providing a means of securing taperingpieces in the jaws of the vise.

In operation either of the vise-heads may be turned upward by simplyreleasing the hand-nut 21 to remove the pressure from the shaft 4, andat the same time the vise may be revolved about the base-plate 1 to anyhori: I00

zontal angle with the table 25 and by tightening the hand-nut 21 theparts made rigid.

The opening and closing of the jaws of the vise are accomplished byrevolving the bar 17 in a manner well known in the art.

The advantage of a multiple vise such as described is that the onedevice answers the equipped at a much less expense.

Various slight modifications may be made purpose of several and a shopmaybe without departing from the spirit of the in-- vention. ThereforeIdo not confine myself to the exact construction shown and described.

Having thus described my invention, I claime 1. In combination, in amultiple vise, a base-plate, a frame, a stationary hollow shaft seatedtherein, means connected to said shaft for securing the same rigidly tothe frame, a downwardly-extendingthreaded boss formed integral with saidshaft, a series of difierential jaws carried by the head of the shaft,a' ribbed saddle-piece mounted on said shaft, a

yoke engaging said saddle-piece for binding the same to the shaft andterminating in a threaded shank, means arranged within the base-platefor engagement with the shank to secure the yoke to the said base-plate,a lon-' gitudinally-movable hollow shaft arranged within thestationaryshaft and provided with a slot to receive said threaded boss, aseriesofdifierential jaws carried by the movable shaft, a screw operatingthrough the head .of

din-ally-mov-able shaft,v and a'screw operating through the head andbore of the movable shaft for moving its jaws toward or away from thejaws of the stationary shaft, substantially as described.

3. In a multiple vise,.the combination, with the bench or support andthe base-plate secured thereto, of the frame rotatably mounted tionaryshaft, a series of diiferential jaws carried by said movable shaft, andmeans operating'within the movable shaft for moving its jaws toward oraway'from the jaws of the stationary shaft, as andfor'thepurposedescribed.

4. In combination, with the bench or support and the base-plate mountedthereon, a

frame rotatably mounted on said base-plate, a stationary hollowshaft'seated insaid frame,

the movable shaft and engaging ln-sald threaded boss, means carried bysaid screw for operating the same to actuate the movable shaft,and meanscarried by the head of the movable shaft for engagement with said.

screw, asand for the purpose described.

2'. In a multiple vise, the combination with the bench or support andthe base-plate se cured to said support, of the frame rotatably mountedon said base-plate, a stationary hollow shaft seated in said frame, asaddle-piece engaging 'said shaft, a yoke engaging said saddle-piece andprovided with a shank ex tending through the base-plate and support, aring arranged within the: base-plate and engaging said shank to hold thesame in en; gagement with the base-plate, a hand-nut mounted on saidshank' for-rigidly securing the parts to the bench or support, a seriesof differential jaws carried by said hollow shaft, a longitudinallymovable hollow shaft arranged within thestationary shaft, a-se'ries' ofdifferential jaws carried by said longituscribin g witnesses.

a series of dliierentlal aws carried by said shaft, a ribbedsaddle-piece mounted upon the shaft, a yoke engaging said saddle-pieceaiid provided-with a shank extending through the baseplate and benchor'support, means carried by said shank for'binding-theparts' to thebench or support, a spring-ring ar-' ranged within the baseplate andengaging said shank for binding the parts together .when'detached' fromthe benchorsupport, a ,longitudinally-movable hollowshaft arranged:within' the stationary hollow shaft, :1. seriesof.differentialjawscarried bysaid movable hollow'shaft, and meansoperating within said movable shaft for actuating the same, as and forthe purpose described.
